Frequently asked questions

Common questions about FSQ from 3G Electric.

What materials are used in FSQ withdrawal sleeves?

FSQ withdrawal sleeves, such as the AHX3220 and AHX2314, are manufactured from chrome steel. This material provides hardness and wear resistance suitable for repeated mounting and dismounting of bearings on shafts. Chrome steel is a standard choice for bearing accessories due to its dimensional stability under load.

What thread sizes are available for FSQ withdrawal sleeves?

FSQ withdrawal sleeves feature metric threads. Common thread sizes include M80x2, M85x2, M110x2, M120x2, M125x2, and M145x2, depending on the sleeve model. These threads are designed to match corresponding lock nuts and facilitate secure axial positioning on shafts.

Are FSQ bearing lock washers compatible with specific lock nuts?

Yes, FSQ bearing lock washers are designed for use with specific lock nuts. For example, the W44 lock washer is compatible with lock nut W44, and the W28 lock washer is compatible with lock nut AN28. This ensures proper engagement and locking of the bearing assembly on the shaft.

What taper ratios are available on FSQ withdrawal sleeves?

FSQ withdrawal sleeves are available with a 1:12 taper, as seen in models like AHX2326 and AHX3122. This taper is standard for adapting bearings with a 1:12 bore taper to cylindrical shafts, allowing for precise interference fit and easy removal.

Can FSQ withdrawal sleeves be used with metric bearings?
